Background Chitosan-based films have emerged as promising sustainable alternatives to conventional petroleum-based films for food packaging. However, there is a lack of a comprehensive bibliometric review of the academic literature on chitosan-based films for food packaging, particularly studies published over the last ten years. Growing concerns about plastic waste and the demand for sustainable and smart packaging have increased academic interest in this field. This study provides a bibliometric review of the literature published from 2015 to 2024 to map the research landscape and guide future studies. Methods Bibliometric data covering the 2015–2024 period were retrieved from the Scopus database using keywords related to “chitosan-based films” and “food packaging”. A dataset of 1,583 publications was analyzed and visualized using VOSviewer (version 1.6.20) and Biblioshiny in the Bibliometrix R package to evaluate publication trends, influential contributors, collaboration networks, keyword co-occurrence, thematic development, and highly cited articles. Results The analysis showed a progressive increase in publications from 2015 to 2024. The study also identified the leading contributors, including countries, institutions, authors, and journals. Keyword analysis, thematic mapping, and highly cited articles clearly indicate that current research hotspots focus on the development of smart packaging, including active and intelligent packaging, as well as the mechanical reinforcement of films. Conclusions To the best of our knowledge, this is the first bibliometric review to examine research trends in Scopus-indexed publications on chitosan-based films for food packaging from 2015 to 2024. The findings may help researchers, organizations, and policymakers understand the development of this field and identify topics for future research.
